connecting the BBB with a 4D display


I am very new to all this, I have a BBB and a 4D systems display (28PTU) and trying to connect them both together but I have no idea how. I couldnt find anything on the homepage and the forum is rather poor.

So I plug the display via the USB port into the BBB which starts the splashscreen of the display but I don’t know how to execute a program or test if it even works.

In the workshop program where I programmed my program there it says it doesn’t recognize the display while scanning through the comm ports.

Any idea how I could do this?
